An array of <i>n</i> monotonically increasing distance values is specified, such that distances[0] is associated with the highest level of detail and distances[<i>n</i>-1] is associated with the lowest level of detail. Based on the actual distance from the viewer to this DistanceLOD node, these <i>n</i> distance values [0, <i>n</i>-1] select from among <i>n</i>+1 levels of detail [0, <i>n</i>]. If <i>d</i> is the distance from the viewer to the LOD node, then the equation for determining which level of detail (child of the Switch node) is selected is: <p> <ul> 0, if <i>d</i> <= distances[0] <br> <i>i</i>, if distances[<i>i</i>-1] < <i>d</i> <= distances[<i>i</i>] <br> <i>n</i>, if d > distances[<i>n</i>-1] </ul> <p> Note that both the position and the array of distances are specified in the local coordinate system of this node.<P><P><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR></TABLE> <A NAME="fields_inherited_from_class_javax.media.j3d.Node"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Fields inherited from class javax.media.j3d.<A HREF="../../../javax/media/j3d/Node.html" title="class in javax.media.j3d">Node</A></B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/media/j3d/Node.html#ALLOW_AUTO_COMPUTE_BOUNDS_READ">ALLOW_AUTO_COMPUTE_BOUNDS_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_AUTO_COMPUTE_BOUNDS_WRITE">ALLOW_AUTO_COMPUTE_BOUNDS_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_BOUNDS_READ">ALLOW_BOUNDS_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_BOUNDS_WRITE">ALLOW_BOUNDS_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_COLLIDABLE_READ">ALLOW_COLLIDABLE_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_COLLIDABLE_WRITE">ALLOW_COLLIDABLE_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_LOCAL_TO_VWORLD_READ">ALLOW_LOCAL_TO_VWORLD_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_LOCALE_READ">ALLOW_LOCALE_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_PARENT_READ">ALLOW_PARENT_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_PICKABLE_READ">ALLOW_PICKABLE_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_PICKABLE_WRITE">ALLOW_PICKABLE_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ENABLE_COLLISION_REPORTING">ENABLE_COLLISION_REPORTING</A>, <A HREF="../../../javax/media/j3d/Node.html#ENABLE_PICK_REPORTING">ENABLE_PICK_REPORTING</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/media/j3d/DistanceLOD.html#DistanceLOD()">DistanceLOD</A></B>()</CODE><BR> Constructs and initializes a DistanceLOD node with default values.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/media/j3d/DistanceLOD.html#DistanceLOD(float[])">DistanceLOD</A></B>(float[] distances)</CODE><BR> Constructs and initializes a DistanceLOD node with the specified array of distances and a default position of (0,0,0).</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/media/j3d/DistanceLOD.html#DistanceLOD(float[], javax.vecmath.Point3f)">DistanceLOD</A></B>(float[] distances, <A HREF="../../../javax/vecmath/Point3f.html" title="class in javax.vecmath">Point3f</A> position)</CODE><BR> Constructs and initializes a DistanceLOD node with the specified array of distances and the specified position.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== -->⌨️ 快捷键说明
